+# netdata go.d.plugin configuration for k8s_kubelet

+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - GLOBAL
+#  - JOBS
+#
+#
+# [ GLOBAL ]
+# These variables set the defaults for all JOBs, however each JOB may define its own, overriding the defaults.

+# The GLOBAL section format:

+# Currently supported global parameters:
+#  - update_every

+# [ JOBS ]
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.

+# IMPORTANT:
+#  - Parameter 'name' is mandatory.

+### configuration
+
+Needs only `url` to kubelet metric-address.
+
+Here is an example:
+
+```yaml
+jobs:
+  - name: local
+    url : http://127.0.0.1:10255/metrics
+
+  - name: remote
+    url : http://100.64.0.1:10255/metrics
+```
+
+For all available options please see module [configuration file](https://github.com/netdata/go.d.plugin/blob/master/config/go.d/k8s_kubelet.conf).
+
+Without configuration, module attempts to connect to `http://127.0.0.1:10255/metrics`
